Weaknesses this control addresses (8)AI-assisted
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-862 | Missing Authorization | 10,200+ | Prevents missing authorization checks for input operations by restricting the capability itself. |
CWE-284 | Improper Access Control | 6,900+ | Directly enforces access control by limiting input capability exclusively to authorized personnel. |
CWE-863 | Incorrect Authorization | 3,900+ | Reduces incorrect authorization decisions by gating all input at the personnel/process level. |
CWE-306 | Missing Authentication for Critical Function | 3,300+ | Ensures critical input functions cannot be reached without prior authorization. |
CWE-285 | Improper Authorization | 1,500+ | Implements authorization checks on who may supply information to the system. |
CWE-425 | Direct Request ('Forced Browsing') | 200+ | Blocks unauthorized direct requests or forced browsing by denying input access to non-authorized actors. |
CWE-807 | Reliance on Untrusted Inputs in a Security Decision | 94 | Reduces reliance on untrusted inputs by ensuring only authorized sources may supply data. |
CWE-642 | External Control of Critical State Data | 18 | Limits external actors' ability to control critical state through input channels. |
